Document Type and Number:
WIPO Patent Application WO/2011/018958
Kind Code:
A1
Abstract:
Disclosed are: a paste for an electron emission source, which enables omission of an activation process and is capable of emitting electrons at a low voltage, while exhibiting excellent adhesion to a cathode substrate; and an electron emission source which uses the paste for an electron emission source. Specifically disclosed is an electron emission source which is produced by subjecting a paste for an electron emission source containing the components (A)-(C) described below to a heat treatment. The electron emission source has cracks and carbon nanotubes project from the surfaces of the cracks.
(A) carbon nanotubes
(B) glass powder
(C) at least one substance selected from the group consisting of metal salts, metal hydroxides, organic metal compounds, metal complexes, silane coupling agents and titanium coupling agents.
